For her virtuous deeds in her previous life, Alice was rewarded with a life in an utopian world, where she didn't have to lift a finger to get anything she wanted.

There is only one catch, always obey the ROOT system, no matter what.

When she broke that taboo, the world fell into chaos. Her ROOT system was warped and changed along with everything around her former home, the place changing into a tower and a territory she has total control in, in exchange of being bound to the place.

Now, she has one duty.

Train the visitors to survive the apocalypse.
